This really is a niche application. It'll be interesting to see if anyone at all downloads it.
My eyesight is deteriorating and I recently started to use my late mother's Ruby magnifier to read the clues of the Sydney Morning Herald cryptic crossword which I attempt over breakfast (but not Friday's one which is usually totally baffling).
I got sick of holding the magnifier so designed and made this stand.
The stand is specialised in two ways, specifically for the Ruby magnifier, and at a height which at minimum magnification shows the full width of the clue and still large enough for me to read it with ease.
Designed in MOI, and made on a Robox using Robox ABS.

Easy to make just make sure that you orient the parts appropriately before printing.
The holes are sized for 3mm screws.
I used 3mm x 8mm long (OAL) button head cap screws.
